Sonance Professional Series PS-C63RTLP is a 70V/100V/8 Ohm selectable In-Ceiling Speaker that features a shallow 4.37” (111mm) construction for installations in restricted spaces such as beneath HVAC ducting. It also features a one-piece bezel-less grille that is magnetically secured and allows for a one-step painting process to simplify installation and minimize visual distraction.
The optional Square Grille Adapter allows speakers to match the aesthetic of square downlights and HVAC grilles to achieve continual sight lines.
A high-excursion 6.5” polypropylene woofer delivers effortless low bass extension, even at high volumes, while the pivoting chambered 1” soft dome tweeter can be directed to ensure accurate coverage, when speaker positioning is compromised.
The PS-C63RTLP features a sealed metal enclosure with back and side knock-outs, removable Euroblock connector with loop-through, and seismic attachment. Additionally, the Sonance PS-C63RTLP is certified for UL 1480 and UL 2043.
